Summary of group differences in model parameters for the temporal discounting Softmax model^a

Parameter	Baseline		Magnitude effect
	Mdiff	dBF	Mdiff	dBF
Log(k)	2.66	116.34	−0.10	0.42
Temp	0.03	1.36	−0.01	0.89

^aFor each parameter, we report mean posterior group differences (M_diff) and BFs (dBF) testing for directional effects on both the baseline parameter in the 100€ condition (left columns) and on the magnitude effect on each parameter (right columns). BFs < 0.33 reflect evidence for placebo < haloperidol, whereas BFs >3 reflect evidence for placebo > haloperidol. For details, see Statistical analyses.
